16x16 Video Crosspoint
Features
The ISL59530 is a 300MHz 16x16 Video Crosspoint Switch.
Each input has an integrated DC-restore clamp and an input
buffer. Each output has a fast On-Screen Display (OSD)
switch (for inserting graphics or other video) and an output
buffer. The switch is non-blocking, so any combination of
inputs to outputs can be chosen, including one channel
driving multiple outputs. The Broadcast Mode directs one
input to all 16 outputs. The output buffers can be individually
controlled through the SPI interface, the gain can be
programmed to x1 or x2, and each output can be placed into
a high impedance mode.
• 16x16 non-blocking switch with buffered inputs and outputs
• 300MHz typical bandwidth
• 0.025%/0.05° dG/dP
• Output gain switchable x1 or x2 for each channel
• Individual outputs can be put in a high impedance state
• -90dB Isolation at 6MHz
• SPI digital interface
• Single +5V supply operation
• Pb-free available (RoHS compliant)
The ISL59530 offers a typical -3dB signal bandwidth of
300MHz. Differential gain of 0.025% and differential phase of
0.05°, along with 0.1dB flatness out to 50MHz, make the
ISL59530 suitable for many video applications.
Applications
• Security camera switching
• RGB routing
The switch matrix configuration and output buffer gain are
programmed through an SPI/QSPI™-compatible three-wire
serial interface. The ISL59530 interface is designed to
facilitate both fast updates and initialization. On power-up, all
outputs are high impedance to avoid output conflicts.
• HDTV routing

(Note)
TAPE & REEL
The ISL59530 is available in a 356 ball BGA package and
specified over an extended -40°C to +85°C temperature range.
The single-supply ISL59530 can accommodate input signals
from 0V to 3.5V and output voltages from 0V to 3.8V. Each
input includes a clamp circuit that restores the input level to
an externally applied reference in AC-coupled applications.

VREF
DC-restore clamp reference input. In an AC-coupled configuration
(DC-Restore clamp enabled), the sync tip of composite video inputs
will be restored to this level. Set to 0.3V to 0.7V for optimum
performance.
In an DC-coupled configuration (DC-Restore clamp disabled), this pin
should be tied to ground.
Do not let the VREF pin float! A floating VREF pin drifts high and, if
the clamp function is enabled, will cause all of the outputs to
simultaneously try to drive ~4V DC into their 150Ω loads.

General Description
Serial Interface
The ISL59530 is a 16x16 integrated video crosspoint switch
matrix with input and output buffers and On-Screen Display
(OSD) insertion. This device operates from a single +5V
supply. Any output can be generated from any of the 16 input
video signal sources, and each output can have OSD
information inserted through a dedicated, fast 2:1 mux
located before the output buffer. There is also a Broadcast
mode allowing any one input to be broadcast to all 16
outputs. A DC restore clamp function enables the ISL59530
to AC-coupled incoming video.
The ISL59530 is programmed through a simple serial
interface. Data on the SDI (serial data input) pin is shifted
into a 16-bit shift register on the rising edge of the SCLK
(serial clock) signal (this is continuously done regardless of
the state of the SLATCH signal). The LSB (bit 0) is loaded
first and the MSB (bit 15) is loaded last (see the “Serial
Timing Diagram” on page 19). After all 16 bits of data have
been loaded into the shift register, the rising edge of
SLATCH updates the internal registers.
The ISL59530 offers a -3dB signal bandwidth of 300MHz.
Differential gain and differential phase of 0.025% and 0.05°
respectively, along with 0.1dB flatness out to 50MHz make
this ideal for multiplexing composite NTSC and PAL signals.
The switch matrix configuration and output buffer gain are
programmed through an SPI/QSPI™-compatible, three-wire
serial interface. The ISL59530 interface is designed to
facilitate both fast initialization and configuration changes.
On power-up, all outputs are initialized to the disabled state
to avoid output conflicts in the user’s system.
Digital Interface
The ISL59530 uses a serial interface to program the
configuration registers. The serial interface uses three
signals (SCLK, SDI, and SLATCH) for programming the
ISL59530, while a fourth signal (SDO) enables optional
daisy-chaining of multiple devices. The serial clock can run
at up to 5MHz (5Mbits/s).
18
While the ISL59530 has an SDO (Serial Data Out) pin, it
does not have a register readback feature. The data on the
SDO pin is an exact replica of the incoming data on the SDI
pin, delayed by 15.5 SCLKs (an input bit is latched on the
rising edge of SLCK, and is output on SDO on the falling
edge of SLCK 15.5 SCLKs later). Multiple ISL59530’s can be
daisy-chained by connecting the SDO of one to the SDI of
the other, with SCLK and SLATCH common to all the daisychained parts. After all the serial data is transmitted
(16 bits*n devices = 16*n SCLKs), the rising edge of
SLATCH will update the configuration registers of all n
devices simultaneously.
The “Serial Timing Diagram” on page 19 and the “SERIAL
TIMING PARAMETERS” on page 19 show the timing
requirements for the serial interface.

Programming Model
The ISL59530 is configured by a series of 16-bit serial control words. The three MSBs (B15 through B13) of each serial word
determine the basic command:

Mapping Inputs to Outputs
Inputs are mapped to their desired outputs using the input/output control word. Its format is:

I3:I0 form the 4-bit word indicating the input channel (0 to 15), and O3:O0 determine the output channel which that input channel
will map to. One input can be mapped to one or multiple outputs. To fully program the ISL59530, 16 INPUT/OUTPUT words must
be transmitted - one for each input channel.
Note: Broadcast Mode must be disabled when configuring input/output mapping. INPUT/OUTPUT words transmitted while in
Broadcast Mode will not be processed correctly and result in corrupt channel mapping when Broadcast Mode is disabled.

Enabling Outputs
The output enable control word is used to enable individual outputs. There are 16 channels to configure, so this is accomplished by
writing 4 serial words, each controlling a bank of four outputs at a time. The bank is selected by bits B9 and B8. The output enable
control word format is:

Setting the ON bit = 0 tri-states the output. Setting the ON bit = 1 enables the output if the Global Output Enable bit is also set (the
individual output enable bits are ANDed with the Global Output Enable bit before they are sent to the output stage).
Setting the Gain
The gain of each output may be set to x1 or x2 using the Gain Set word. It is in the same format as the output enable control word:

are restored.
Control Word
The ISL59530’s power-on reset disables all outputs and places the part in a low-power standby mode. To enable the device, the

The Clamp bit enables the input clamp function, forcing the AC-coupled signal’s most negative point to be equal to VREF.
Note: The Clamp bit turns the DC-Restore clamp function on or off for all channels - there is no DC-Restore on/off control for
individual channels. The DC-Restore function only works with signals with sync tips (composite video). Signals that do not have
sync tips (the Chroma/C signal in S-video and the Pb, Pr signals in Component video), will be severely distorted if run through a
DC-Restore/clamp function.

For this reason, the ISL59530 must be in DC-coupled
mode (Clamp Disabled) to be compatible with S-video
and component video signals.
Bandwidth Considerations
Wide frequency response (high bandwidth) in a video
system means better video resolution. Four sets of
frequency response curves are shown in Figure 47.
Depending on the switch configurations and the routing (the
path from the input to the output), bandwidth can vary
between 100MHz and 350MHz. A short discussion of the
trade-offs — including matrix configuration, output buffer
gain selection, channel selection, and loading — follows.
Linear Operating Region
In addition to bandwidth optimization, to get the best linearity
the ISL59530 should be configured to operate in its most
linear operating region. Figure 48 shows the differential gain
curve. The ISL59530 is a single supply 5V design with its
most linear region between 0.1 and 2V. This range is fine for
most video signals whose nominal signal amplitude is 1V.
The most negative input level (the sync tip for composite
video) should be maintained at 0.3V or above for best
operation.

FREQUENCY (Hz)
FIGURE 47. FREQUENCY RESPONSE FOR VARIOUS MODES
In multiplexer mode, one input typically drives one output
channel, while in broadcast mode, one input drives all 16
outputs. As the number of outputs driven increases, the
parasitic loading on that input increases. Broadcast Mode is
the worst-case, where the capacitance of all 16 channels
loads one input, reducing the overall bandwidth. In addition,
due to internal device compensation, an output buffer gain of
x2 has higher bandwidth than a gain of x1. Therefore, the
highest bandwidth configuration is multiplexer mode (with
each input mapped to only one output) and an output buffer
gain of x2.
The relative locations of the input and output channels also
have significant impact on the device bandwidth (due to the
layout of the ISL59530 silicon). When the input and output
channels are further away, there are additional parasitics as
a result of the additional routing, resulting in lower
bandwidth.
The bandwidth does not change significantly with resistive
loading, as shown in the “Typical Performance Curves”.
However several of the curves demonstrate that frequency
response is sensitive to capacitance loading. This is most
significant when laying out the PCB. If the PCB trace length
between the output of the crosspoint switch and the backtermination resistor is not minimized, the additional parasitic
capacitance will result in some peaking and eventually a
reduction in overall bandwidth.
21
In a DC-coupled application, it is the system designer’s
responsibility to ensure that the video signal is always in the
optimum range.
When AC coupling, the ISL59530’s Clamp (also called “DC
restore”) function automatically and continuously adjusts the
DC level so that the most negative portion of the video is
always equal to VREF.
A discussion of the benefits of the DC restoration function
begins by understanding the Clamp circuit shown in
Figure 49. The incoming video signal is typically terminated
into 75Ω, then AC coupled through C1, at which point it is
connected to the base of the buffer’s differential pair. These
components form the video path.
The Clamp function consists of Q1, D1, Q2, D2, the two
current sources, and the 3 switches controlled by the Clamp
Enable signal. The VREF voltage is level-shifted up two
diode drops (Q1 and D1) to the base of Q2. If the voltage at
the cathode of D2 goes below VREF, Q2 and D2 will turn on,
keeping the INx voltage at VREF. If the voltage at INx is
greater than VREF, Q2 and D2 are off and the INx node is
high impedance. This is how the clamp function forces the
lowest portion of the video signal (the sync tip) to always be
equal to or greater than VREF.
To make sure that the sync tip is always equal to (not equal
to or greater than) VREF; i1 is constantly sinking ~2µA of
current from C1. This causes each sync tip to be slightly
lower voltage than the previous sync tip, causing Q2 and D2
to turn on at each sync tip and raise the voltage to VREF. The
2µA pull-down with a 0.1µF capacitor and a 15kHz HSYNC
frequency results in 1.3mV of “droop” across every line, or
FN6220.6

0.2% of the video signal. Because 1.3mV is only 0.2% of a
0.7V video signal, this droop is imperceptible to the human
eye.
the result of CIN = 0.1µF delivering acceptable droop and
CIN = 0.001µF producing excessive droop.
When the clamp function is disabled in the CONTROL
register (Clamp = 0) to allow DC-coupled operation, the
ICLAMP current sinks/sources are disabled and the input
passes through the DC Restore block unaffected. In this
application, VREF may be tied to GND.
Overlay Operation
The ISL59530 features an overlay feature that allows an
external video signal or DC level to be inserted in place of
that output channel’s video. When the OVERN signal is
taken high, the output signal on the OUTN pin is replaced
with the signal on the VOVERN pin.

There are several ways the overlay feature can be used.
Toggling the OVERN signal at the frame rate or slower will
replace the video frame(s) on the OUTN pin with the video
supplied on the VOVERN pin.
Another option (for OSD displays, for example), is to put a
DC level on the VOVERN line and toggle the OVERN signal
at the pixel rate to create a monocolor image “overlaid” on
channel N’s output signal.

FIGURE 49. DC RESTORE BLOCK DIAGRAM
This is how the video is “DC-restored” after being AC
coupled into the ISL59530. The sync tip voltage will be equal
to VREF on the right side of C1, regardless of the DC level of
the video on the left side of C1. Due to various sources of
offset in the actual clamp function, the actual sync tip level is
typically about 75mV higher than VREF (for VREF = 0.4V).
Finally, by enabling the OVERN signal for some portion of
each line over a certain amount of lines, a picture-in-picture
function can be constructed.
It’s important to note that the overlay inputs do not have the
DC Restore function previously described - the overlay
signal is DC coupled into the output. It is the system
designer’s responsibility to ensure that the video levels are
in the ISL59530’s linear region and matching the output
channel’s offset and amplitude. One easy way to do this is to
run the video to be overlaid through one of the ISL59530’s
unused channels and then into the VOVERN input.
The OVERN pins all have weak pull-downs, so if they are
unused, they can either be left unconnected or tied to GND.

CIN = 1nF
FIGURE 50. DC RESTORE VIDEO WAVEFORMS
It is important to choose the correct value for CIN. Too small a
value will generate too much droop, and the image will be
visibly darker on the right than on the left. A CIN value that is too
large may cause the clamp to fail to converge. The droop rate
(dV/dt) is i1/CIN volts/second. In general, the droop voltage
should be limited to <1 IRE over a period of one line of video; so
for 1 IRE = 7mV, IB = 10µA maximum, and an NTSC waveform
we will set CIN > 10µA*60µs/7mV = 0.086µF. Figure 50 shows

With a large number of switches, it is possible to exceed the
+150°C absolute maximum junction temperature under
certain load current conditions. Therefore, it is important to
calculate the maximum junction temperature for an
application to determine if load conditions or package types
need to be modified to assure operation of the crosspoint
switch in a safe operating area.
The maximum power dissipation allowed in a package is
determined according to Equation 1:

• TAMAX = Maximum ambient temperature = +85°C
• θJA = Thermal resistance of the package
